Hi, we today saw a Win2k8 VM with first device IDE and second device SCSI crash reprocably during boot. Win2k8 32-bit Server was installed with IDE only. The second SCSI device was added later. Here is the output and commandline: Aug 5 20:42:55 172.21.59.142 exec: /usr/bin/qemu-kvm-0.12.4 -net tap,vlan=726,script=no,downscript=no,ifname=tap0 -net nic,vlan=726,model=rtl8139,macaddr=52:54:00:fe:00:bf -drive format=host_device,file=/dev/mapper/iqn.2001-05.com.equallogic:0-8a0906-e4ce1ab04-3ce7a1250354c545-p01-w2k8,if=ide,boot=on,cache=none,aio=native -drive format=host_device,file=/dev/mapper/iqn.2001-05.com.equallogic:0-8a0906-319e1ab04-39a7a1250204c503-test2,if=scsi,boot=off,cache=none,aio=native -m 4096 -smp 4 -monitor tcp:0:4001,server,nowait -vnc :1 -name 'W2K8-01' -boot order=dc,menu=off -k de -pidfile /var/run/qemu/vm-200.pid -mem-path /hugepages -mem-prealloc -cpu qemu64,model_id='Intel(R) Xeon(R) CPU L5640 @ 2.27GHz',-nx -rtc base=localtime,clock=vm -vga cirrus -usb -usbdevice tablet Aug 5 20:43:06 172.21.59.142 kvm: lsi_scsi: error: Unhandled writeb 0xff = 0x0 Aug 5 20:43:06 172.21.59.142 kvm: lsi_scsi: error: Unhandled writeb 0x100 = 0x0 Aug 5 20:43:06 172.21.59.142 kvm: lsi_scsi: error: Unhandled writeb 0x101 = 0x0 Aug 5 20:43:06 172.21.59.142 kvm: lsi_scsi: error: Unhandled writeb 0x102 = 0x0 Aug 5 20:43:06 172.21.59.142 kvm: qemu-kvm-0.12.4: /usr/src/qemu-kvm-0.12.4/hw/lsi53c895a.c:512: lsi_do_dma: Assertion `s->current' failed.
